This invention relates to-improvements in wrist watch bands of the bracelet type, adaptable for.

usebyself-fastening about the wrist and capable of se1-adiustmentto the average: size. of Wrists;

It is common knowledge that wrist watch straps,- in generalhaving leather components are rather. perishable and require constant replacements.

more particularly during the summer season. Furthermore, watch straps fabricated entirely out of metal are very expensive.

My invention will permit the use of wrist watch bands which are not only attractive but inexpensive at the same time and with reasonable care they will outlast any other wrist strap many times over; and yet will always remain clean and sanitary.

I attain these objects as illustrated in the accompanying drawing and more particularly set forth in the appended claims.

Fig. 1 is a plan view of the blank from which the Wrist band is made.

Fig. 2 is a plan view of the auxiliary attachments removed from the band.

Fig. 3 is a side View of the band and the auxiliary attachments affixed to a. Watch.

Fig. 4 is a view of one of the rectangular loops attached to a flexible metal strip.

Fig. 5 is a perspective View of a portion of the band showing a ribbed surface on the underside of the band as a structural modification.

Similar numerals refer to similar parts throughout the several views.

Fig. 1 depicts a wrist watch band I, which can either be fabricated 'from standard sheet stock of plastic material or molded by injection or extrusion processes and having sufficient thickness to contribute to fiexures and resiliency when formed into a substantially C-shaped member to be adaptable to a wrist fitting contour as shown in Fig. 3, and having the free ends II] and II of the band I, sufficiently spaced to permit their passage over the wrist only when sprung apart to allow the band to be slipped over the wrist but in absence of such strain, the band will normally contract to snugly fit the wrist and retain its C-shaped contour as shown in Fig. 3.

Fig. 2 depicts the auxiliary instrumentalities 6 ,Claims. (01. 224-:4.)

Figi 3 depictsthe C-shapedband in combination with itswatch-carryingmedia 4, 5, 6, I and B afllxed to the band'l.

Fig. 4 depitcs'one of the rectangular loops 8, connectedto the: flexible element I, for slidable attachment tothe bandl and for detachable attachment to the spring-like member 4 as complemental parts for fixation of a watch I:2 to the bandli I Figm5" depicts a modified embodiment of the blank I; from which the band may be made,

namely various types of thermo-plastics, from metal or from any other relatively light, flexible and shape-maintaining material of desired characteristics and consisting of a plurality of rib formations I3 on the underside of band I, to permit fiexural strength as well as ventilation at its surface contact with the skin when the wrist band is in use.

I prefer to carry out the feature of my invention as shown in Fig. 3, from which it will be clearly seen that the auxiliary detachably attachable elements 4, 5, B, I and 8 are respectively assembled together to form a union thereof for adaption of a wrist watch I2, to it as a whole and in co-operation with the band I. The rectangular loops 8 may be endless loops or rings of sprung wire or of other metal, inserted within the looped or turned-over ends 5 of the strap members I. It will be noted that the end portions 2 of the band I are tapered up to the points indicated at 3, and the loops 8 are of such size that they will slide freely on the tapered end portions of the band I, but will be halted on their movement toward one another upon reaching the points 3. Thus, the ends 3 of the tapered parts of the band I constitute actual shoulders which limit the movement of the outer ends of the straps I toward the center of the band I.

One of the free ends III, of band I, is inserted alternately through one of the rectangular loops 8, up to limits 3 of the taper 2, on band I. Each of the loops 5 of strips Ibeing attached at one of their extremities to loop 8 and looped for detachable attachment to the spring-like element 4 at their respective extremities 6. When each of the loops and 6 have been thus respectively assembled together in sequence, the strips '1, will have been connected to the spring element 4 and to the rectangular loops 8 to form a secure union and an aggregated unitary means for the adaptation of a wrist watch to the band I. The metal strips 1, are extended over the conventional spring bars of the watch and passed in back of the watch to thereby attach the watch to the said unitary elements 4, 5, 6, I and 8, in the manner clearly shown in Fig. 3. Such means will permit a wrist watch of almost any size and shape to be centrally accommodated and positioned on the wrist band I. L j

In view of the instant embodiments of this invention, I new claim:

1. A wrist-band of the character described comprising, a substantially c-shaped stiff but springy band to fit about the wrist, said band having its ends spaced apart, said band varying in width and being narrowest near its ends, an extensible strap for engagement with a watch, the strap having loops at its ends freely fitting over the narrow portions of the band and restrained from movement toward the center of the band by the wider portions of the band.

2. In a wrist band as provided for in claim 1, wherein the strap consists of a plurality of strap sections connected by an expansible spring.

3. In a wrist band of the character described, a C-shaped band of stiff but springy material having end portions of reduced width and a central wider portion, a flexible and extensible strap provided at its opposite ends with loops fitting over the end portions of the band, said loops being too small internally to fit about the central wider portion of the band, whereby said loops are normally held at the junctions of the wide and narrow parts of the band, and a watch engaged by the strap and held thereby against the face of the band.

4. In a wrist band of the character described,

a c-shaped band of stiif but springy material, a pair of strap members provided with loops at their ends, an expansible spring located between the strap members and having its ends attached to a loop at one end of each of the straps, a ring in the loop at the other end of each of the straps, said rings fitting around the band, shoulders on the band for limiting the movement of the rings toward the center of the band, and a watch engaged by the straps and held thereby against the outer face of the band.

5. In a wrist band as provided for in claim 4, whereby the watch overlies the spring and confines the spring between it and the face of the band and covers and conceals said spring.

6. In a wrist band of the character described, a C-shaped band of stiff but springy material, said band having a central wide part and narrow end parts, the junctions of said parts defining spaced shoulders on the band, a resilient strap having rings at its ends fitted over the ends of the band and restricted against movement toward the center of the band by the inability of the rings to pass the shoulders on the band in a direction toward the center of the band.
